Original tested and certified filters
I've been using the Brondell RC100 Circle RO system (originally purchased from Costco) for almost a decade now. As you can imagine, I have replaced the filters and the RO membrane numerous times over the years.Yes, this filter set is expensive, and you can find replica filters manufactured in China for about $20 less, but... These official filters are tested and certified to meet NSF/ANSI standards, which guarantees their performance. Would you really risk your health to save $20? Who knows exactly how or where those replica filters were manufactured.

Love my Brondell
I love my Brondell reverse osmosis and they need the filters changed twice a year. The quality is outstanding and they take the nasty chemical taste away from my water. I wish they would lasted longer but that’s the way it works. Instructions are clear and the filters for like a glove. I also like that it comes with a replacement battery.

Good value for money
Works well for 6-9 months. Recommend changing when you start feeling the change in taste

Save money, verify need to change filters
Purchased and installed a Brondell Circle RO system in August 2022.We're still using the original cartridges, I purchased a replacement set just in case and they are still sealed in the box.Changing them every 6 months is (probably) a waste of money.First, buy yourself a TDS meter (not a referral link, plenty of others on Amazon but this is the one I got- https://www.amazon.com/gp/product/B07QLZ6DT5 ) and test your water from the faucet versus out of the reverse osmosis filter. Our water is normally around 60 ppm, from the Brondell it is about 6-7 ppm.After a year it is still 6-7 ppm TDS. At exactly 6 months and again at 12 months the "change filter" light on the faucet started blinking. I don't think it is based on water usage, it is on a timer. All I do is remove the battery, wait 30 seconds and reinstall.Your mileage may vary, obviously our faucet water is naturally pretty low on contaminants (only reason we got the RO is that 2 of those contaminants are arsenic and manganese so it's nice to reduce those to safer levels) so if your tap water has more stuff in it your filters may get clogged up faster. But if you have a TDS meter showing you the filter is doing its job AND your water flow is not slowing down changing the cartridges is unnecessary.Hope that helps someone concerned about the high cost of these oem filters.
